摘要
用超声分散的方法将Ｆｅ２Ｏ３超微粒分散于硬脂酸／正己烷／氯仿溶液中，用ＬＢ膜技术进行组装。结果表明：Ｆｅ２Ｏ３超微粒能均匀地分散在有机溶剂中，并且能够被硬脂酸包裹；Ｆｅ２Ｏ３超微粒／硬酯酸单分子膜的成膜性能良好，Ｆｅ２Ｏ３超微粒／硬脂酸复合ＬＢ膜具有层状结构；在Ｆｅ２Ｏ３超微粒的晶格结构和硬脂酸单分子膜的晶格结构相匹配的情况下，Ｆｅ２Ｏ３超微粒能够被有序组装。
The Fe 2O 3 ultrafine particles were dispersed in solution of stearic acid/n hexane/choroform by the ultrasonic method,and fabricated by the Langmuir Biodgett film technology.The results showed that Fe 2O 3 ultrafine particles were uniformly dispersed in the orangic solvents,and coated by stearic acid.The film forming characterization of the Fe 2O 3 ultrafine particles/stearic acid monolayer was fine,the Fe 2O 3 ultrafine particles/stearic acid composite LB film had lamellar structure.The Fe 2O 3 ultrafine particles were regularly arranged in the crystalline structure of Fe 2O 3 ultrafine particles being arrayed stearic acid monolayer.
